Pragma Device in Upper Limb Rehabilitation

Abstract

Introduction. PNF patterns are one of the physiotherapeutic methods used in upper limb rehabilitation. Intensification of the effect can be achieved by application of additional resistance. Muscles of the therapist are usually the resistance generator, but in this case there is no possibility to make objective estimation of the applied force value.

Material and method. In the present study using of accordingly fixed rubbers with different modulus of elasticity is proposed to monitor the resistant overcame by patient’s muscles. Values of these forces were determined, both at the beginning and the end of the motion patterns, using six different rubbers.

Results . Study shows that a possibility of choices of the initial protraction and a color of rubber allows a smooth and controlled increase of additional forces of resistance along with progress of the treatment.

Conclusions. Knowledge of the value of these forces allows an objective assessment of the patient’s motor system abilities.
